What are worksets used for in Revit?

Worksets in Revit are primarily used to manage and collaborate on large projects. When working with extensive models that involve multiple team members, worksets allow for organized division of the project into manageable sections. Each team member can work on different parts of the project simultaneously without conflicts, as worksets provide a way to control access to various elements of the model.

This capability is crucial for improving workflow efficiency in collaborative environments where multiple users make changes simultaneously. It enables features such as worksharing, where changes made by one team member can be updated and synchronized with the work of others, ensuring that everyone is working with the latest information.

While the other options involve various functionalities within Revit, they do not specifically pertain to the concept of worksets. For example, creating 3D visualizations, connecting to external databases, and importing CAD drawings are important features of Revit, but they do not address how worksets facilitate teamwork and organization within a large project context.
